flopped set facing flush completing turn 3 way

Hi.

I would usually bet Turn myself with a set in a heads up pot. This hand gets trickier since it's 3way, I think the likelihood that someone has a flush is significantly higher so I am fine with the check.

We also have ~20% equity vs a flush anyway, to hit a full house or quads. And we are getting slightly worse than 25% pot odds so assuming we do have a little implied odds, it's more than enough to call here.

River is tricky. He can have flushes here, but pot odds are too good, and I think given his sizing, I would not be surprised to see 33 sometimes, and also maybe some 2 pairs.

Another thing working in your favour is that he calls from MP, which should significantly reduce the number of speculative hands in his range. For example, I may call 78s in the BU vs UTG raise but I'm probably always folding or 3betting in MP. I think a c/c here could be reasonable.

Thanks.
